Create a Customer Programmatically in Magento 2

Create a model file Customer.php under your custom module and add the below code.

<?php
namespace Codextblog\Customer\Model;

use Magento\Customer\Api\AccountManagementInterface;
use Magento\Customer\Model\AddressFactory;
use Magento\Customer\Model\CustomerFactory;
use Magento\Customer\Model\ResourceModel\Address;
use Magento\Framework\Exception\AlreadyExistsException;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Framework\Stdlib\DateTime\TimezoneInterface;
use Magento\Store\Model\StoreManagerInterface;

class Customer
{
    /**
     * @var AccountManagementInterface
     */
    protected $accountManagement;
    /**
     * @var StoreManagerInterface
     */
    protected $storeManager;
    /**
     * @var CustomerFactory
     */
    protected $customerFactory;
    /**
     * @var \Magento\Customer\Model\ResourceModel\Customer
     */
    protected $customerResource;
    /**
     * @var AddressFactory
     */
    protected $addressFactory;
    /**
     * @var Address
     */
    protected $addressResource;
    /**
     * @var TimezoneInterface
     */
    protected $timezone;

    /**
     * Customer constructor.
     * @param AccountManagementInterface $accountManagement
     * @param StoreManagerInterface $storeManager
     * @param CustomerFactory $customerFactory

     * @param AddressFactory $addressFactory
     * @param Address $addressResource
     * @param TimezoneInterface $timezone
     */
    public function __construct(
        AccountManagementInterface $accountManagement,
        StoreManagerInterface $storeManager,
        CustomerFactory $customerFactory,
        \Magento\Customer\Model\ResourceModel\Customer $customerResource,
        AddressFactory $addressFactory,
        Address $addressResource,
        TimezoneInterface $timezone
    ) {
        $this->accountManagement = $accountManagement;
        $this->storeManager = $storeManager;
        $this->customerFactory = $customerFactory;
        $this->customerResource = $customerResource;
        $this->addressFactory = $addressFactory;
        $this->addressResource = $addressResource;
        $this->timezone = $timezone;
    }

    /**
     * @param array $post
     * @return \Magento\Customer\Model\Customer
     * @throws AlreadyExistsException
     * @throws NoSuchEntityException
     */
    public function createCustomer(array $post)
    {
        $store = $this->storeManager->getStore();
        $websiteId = $this->storeManager->getStore()->getWebsiteId();
        $customer = $this->customerFactory->create();
        $customer->setWebsiteId($websiteId)
            ->setStore($store)
            ->setFirstname($post['firstname'])
            ->setLastname($post['lastname'])
            ->setEmail($post['email'])
            ->setForceConfirmed(true);
        
        $password = $this->getRandomPassword();
        $customer->setPassword($password);
        
        $dob = $post['dob'];
        if (!empty($dob)) {
            $dob = $this->timezone->date($dob)->format('Y-m-d');
            $customer->setDob($dob);
        }

        try {
            //save customer
            $this->customerResource->save($customer);
            if ($customer->getId()) {
                //save customer address
                $customerAddress = $this->addressFactory->create();
                $customerAddress->setCustomerId($customer->getId())
                        ->setFirstname($post['firstname'])
                        ->setLastname($post['lastname'])
                        ->setCountryId($post['country_id'])
                        ->setRegionId($post['region'])
                        ->setPostcode($post['postcode'])
                        ->setCity($post['city'])
                        ->setTelephone($post['phone'])
                        ->setStreet([
                            '0' => $post['street'][0], // required
                            '1' => $post['street'][1] // non-required
                            ])
                        ->setIsDefaultBilling('1')
                        ->setIsDefaultShipping('1');
                $this->addressResource->save($customerAddress);
            }
            return $customer;
        } catch (AlreadyExistsException $e) {
            throw new AlreadyExistsException(__($e->getMessage()), $e);
        } catch (\Exception $e) {
            throw new \RuntimeException(__($e->getMessage()));
        }
    }

    public function getRandomPassword($length = 8)
    {
        $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789$#@";
        return substr(str_shuffle($chars), 0, $length);
    }
}

Here we have developed one function called createCustomer which is receiving customer data. Using those data we are creating a customer along with a customer address. We are setting a random password for a new customer that can be reset by the customer itself.
